TA --
Save did the trick. So simple.
Thank you very much

You don't need to close AB. Just use save or save all.

I recently noticed, with 5.30.4, something that may be related to the
p roblem you are having. Maybe not.
After a walk forward test, ~~~ISEQUITY and ~~~OSEQUITY are not written
to disk until AB is closed. Same goes for ~~~EQUITY after a
backtest. This is driving me up a wall. I used to copy and rename
these files for safe keeping while AB was running. Now I have to
close AB first. Very inconvenient.

Hi,
Is is possible that the AB OLE Automation Object Model call
ExportImage() is broken in AB 5.30.4?
Despite everything I could think of to try, the images always come
out
blank, like those attached.
Neither of the codes below work, and yet each was said to work on the
list in the past.
Operational attempts have included:
AB Open Dbl-Click on script
AB Open Run script from command window
AB Closed Dbl-Click on script
AB Closed Run script from command window
Results are always either: server error, AB crash, or it runs and
produces the blank chart.
When AB is open, it doesn't matter what layout/chart is up. Still
no joy.
What could be (not) happening here???
